[0017] [1-1. Structure]

[0018] The wireless communication device 1 for a vehicle to which the present disclosure is applied is mounted on a vehicle such as a passenger car, and communicates with the outside of the vehicle. In particular, the wireless communication device 1 for a vehicle is used when performing a V2X (Vehicle to X: Internet of Vehicles) service that communicates with a certain device inside or outside the vehicle.

[0019] The vehicle wireless communication device 1 has a function of transmitting radio waves, a function of receiving radio waves, a function of communicating inside the vehicle, and a function of positioning. The wireless communication device 1 for a vehicle is configured, for example, as a single module component, thereby reducing its size and weight.

[0020] If the vehicle wireless communication device 1 is reduced in size and weight, the surface area generally tends to decrease, making it difficult to dissipate heat, and it becomes difficul...

Abstract

An aspect of the present disclosure provides a vehicular wireless communication device (1) which is mounted on a vehicle and performs communication with the outside of the vehicle. The vehicular wireless communication device (1) is provided with: a radio wave transmitting unit (33) having the function to transmit radio waves; a radio wave reception unit (33) having the function to receive radio waves; a positioning unit (34) having the function to perform positioning; a temperature acquiring unit (S110) configured to acquire the temperature of the vehicular wireless communication device; and a function control unit (S130, S240) configured to suppress or resume a plurality of functions among the function to transmit radio waves, the function to receive radio waves, and the function to perform positioning, in response to the temperature.

Description

[0001] Cross Reference to Related Applications: This international application claims priority from Japanese Patent Application No. 2019-036154 filed with the Japan Patent Office on February 28, 2019, and the entire contents of Japanese Patent Application No. 2019-036154 are incorporated by reference to this international application. technical field [0002] The present disclosure relates to a wireless communication device for a vehicle that communicates with the outside of the vehicle. Background technique [0003] Patent Document 1 below discloses a technology for controlling transmission power during communication in accordance with temperature and sunlight amount in a wireless communication device for a vehicle. [0004] Patent Document 1: Japanese Patent No. 6160246 [0005] However, in recent years, size and weight reduction of wireless communication devices for vehicles has been demanded. In addition, there is a tendency that the functions of the vehicle wireless c...
